Product Description

The Automatic Recirculation Valve (ARV) is used in various industrial applications involving centrifugal pumps. Its primary purpose is to ensure the pump's operational integrity and prevent damage during low flow conditions. Here are some common applications and purposes of the ARV:

Pump Protection: The ARV safeguards centrifugal pumps from running dry, which can lead to overheating, cavitation, and eventual pump failure. By diverting a portion of the discharge flow back to the pump's inlet, the ARV ensures a minimum flow is maintained, providing lubrication and cooling to critical pump components.

Flow Control: In systems where maintaining a minimum flow rate is essential for efficient pump operation, the ARV acts as a flow control device. It ensures that the required flow is achieved and sustained, preventing pump instabilities and maintaining optimal pump performance.

System Safety: The ARV contributes to the overall safety of industrial systems by preventing potential hazards caused by low flow situations. By maintaining a continuous flow, it helps prevent equipment malfunctions, process disruptions, and potentially dangerous conditions in sectors such as oil and gas, chemical processing, and power generation.

Process Reliability: Industries that rely on centrifugal pumps, such as refineries and water treatment plants, require a consistent flow rate for their processes to operate reliably. The ARV ensures a steady flow even when demand fluctuates, enhancing system stability and minimizing the risk of downtime or damage to critical equipment.

Energy Efficiency: By maintaining a minimum flow through the pump, the ARV helps optimize energy consumption. It prevents excessive power consumption during low flow conditions and ensures that the pump operates at its designed efficiency range, resulting in energy savings and cost reduction.

Overall, the ARV is employed in situations where maintaining pump integrity, ensuring continuous flow, protecting equipment, and promoting efficient operation are crucial requirements.

Centrifugal Pump Protection Scenarios Using ARC Valve (ARV)

Three protection ways for pump

 

Continuous Circulating System

System Safety Valve Flow Control Centrifugal Pump

Minimum requirement of continuous circulating system pump is unrelated to the discharge of Process flow changes system. After setting of minimum flow, through orifice plate directly backflow to a storage tank. Although continuous minimum flow circulation can protect the pump very good, the pump must provide greater power output to ensure system process flow plus recycle flow, which causing additional energy waste.

 

Control Circulating System

System Safety Valve Flow Control Centrifugal Pump

Control circulatory system is assembly by the check valve, flow gauge, minimum flow control valve, control circulation system, control circulation system can provide minimum flow protection, when process flow is greater than the minimum flow of the pump, loop closed, no extra energy loss. But the system is complex, control components, purchase, installation, maintenance cost is higher.

 

Automatic Recirculation Control Valve

System Safety Valve Flow Control Centrifugal Pump

Automatic recirculation valve set check valve, flow perception, bypass control valve, multi-stage step-down in one, do not need power, control system and wiring, essential safety. Taking up small space, reducing the possibility of high-speed fluid to malfunction to a minimum, with lower installation and maintenance cost, It is the priority pump protection way of the modern industrial process.

The Main Advantages Of AR Series Automatic Recirculation Control Valve

ZD series ARC valve is suitable for bypass with high-pressure differential, a maximum pressure differential is 30MPa, and the specific choice is determined by the factory. Multistage decompression type M type bypass can eliminate noise made by high-speed flow medium, prevent damage of cavitation erosion, and braising to valve components.

Automatic Recirculation Valve Working Principle

According to the difference of inductive main flow, the main valve disc check cone of the ARC valve will automatically move to a certain position. At the same time, the main valve disc drives the bypass valve stem, transfers the movement of the main valve disc to bypass, through control bypass valve disc position, changes the bypass throttling area, so as to control bypass flow. When the main valve disc back into the valve seat closed, all flow backflow through the bypass. When the valve discs rise to the top position, the bypass is fully closed, all the flow of pump flow to the processing system. This valve set four functions in one body.

  • Flow perception: ARC valve main valve disc can automatically perceive the main flow of the processing system, thereby according to the flow to determine the position of the main valve disc and bypass disc.
  • Recirculation control: ARC valve can inhaled pump normal operation required minimum flow into storage device through the bypass, so as to adjust pump H - Q characteristics, to realize recycling.
  • Bypass multistage pressure reducing: bypass control system can reduce the backflow medium from the high-pressure pump outlet to appropriate backflow to the low-pressure storage device with low noise small wear.
  • Check: The automatic recirculation valve also has a check valve effect, preventing the liquid backflow to the pump body. Bypass non-return function is standard.
  • A special bypass size can be customized. The max flow rate of the bypass is subject to the max Kv value.
